The following description will enable others to understand the maimerof producing my improved fertilizer.

I take, say, one part of gas liquor, three parts of blood, andone five-hundreth part of sulphuric acid, and to these substances I add an equal quantity of dry ground phosphate of lime, mix the whole thoroughly together, and then evaporate to dryness.

It should be understood that the compound of blood, gas liquor, and sulphuric acid forms a fluid, or, --semi-fluid, and that while in this condition the phosphate should bra-added to and thoronghlymixed with it.
